Pioneer integrates Class D3 digital amplification into two of its flagship Pioneer branded receivers, the SC-1222 (7.2-channel) and SC-1522 (9.2-channel).

Pioneer's Class D3 amplifier, built into the SC receivers, generates immense power without sacrificing sound quality and performance. The exclusive class D technology requires less energy than competitive models yet produces more simultaneous power output, and is designed to maximize the audio potential of uncompressed sources such as Blu-ray Disc titles and high-definition audio content distributed on the Internet.

The amplifier section also uses a Direct Signal Path Design, configured with all of its internal components to have the shortest audio signal path possible, eliminating EMI filters, feedback loops, and current limiters that were necessary on previous designs. This results in a reduction of ringing distortion and noise, especially in the high frequency audio band. The receivers can produce up to 140 Watts per channel of power with great detail and high dynamic range.

The receivers are also built with custom installation features that offer users and installers multi-room setup options, multiple HDMI inputs and PC Setup control, as well as the latest technologies including Apple's AirPlay, DLNA 1.5, Windows 7 compatibility, Internet radio and Advanced MCACC auto room calibration.
